Some Phones Are Dead (No Dial Tone or Lights)

What to do:
Test the outlet by plugging in an appliance that you know is working,
for example, a lamp or radio.
■
If the appliance does not work, the outlet is faulty. If possible, plug the
control unit into a different outlet. Check the circuit breaker or call an
electrician.
■
If the appliance works, the wiring may be faulty elsewhere in the system.

charges may apply).
Some Phones Are Dead
(No Dial Tone or Lights)
8
Possible Cause 1: The telephones are not receiving power.
What to do: Check that each telephone is plugged into a telephone wall jack
known to be working.
■
If the phones now have dial tone and lights, there may be a problem with
the system wiring or the control unit associated with the faulty phone(s).
Call the Lucent Technologies Helpline at 1 800 628-2888 (consultation
charges may apply).
■
If the phones are still dead, go to Possible Cause 2.
Possible Cause 2: For single-line telephones, the Idle Line Selection may be set
incorrectly. (If not a single-line telephone, skip to Possible Cause 4.)
What to do: Use centralized telephone programming to ensure that the
Ringing/Idle Line Preference is set to On (see Chapter 5 in
System
Programming). Check to see whether the phone now has dial tone.
■
If the phone receives dial tone, you have solved the problem.
■
If the phone is still dead, go to Possible Cause 3.
Possible Cause 3: For single-line telephones, the Auto Line Selection may be set
incorrectly; see Chapter 5 in System Programming. (If not a single-line telephone,
skip to Possible Cause 4.)
What to do: Use centralized telephone programming to set the Auto Line
Selection for the extension. Check to see whether the phone now has dial tone.
■
If the phone receives dial tone, you have solved the problem.
■
If the phone is still dead, go to Possible Cause 5.
